18 Sep 2001 | | Journal: | In "Science of Metastable and Nanocrystalline Alloys" edited by A.R. Dinesen et al., ISBN 87-550-2916-7, p. 127-139 (Risoe National Laboratory, Roskilde, Denmark, 2001) | | Subject: | Materials Science | cond-mat.mtrl-sci | | Affiliation: | CAMP and Department of Physics, Technical University of Denmark | | Abstract: | In recent years it has become possible to study the properties of nanocrystalline metals through atomic-scale simulations of systems with realistic grain sizes. A brief overview of the main results is given, such as the observation of a reverse Hall-Petch effect - a softening of the metal when the grain size is reduced. The limitations of computer simulations are discussed, with a particular focus on the factors that may influence the reliability of this kind of simulations. | | Source: | arXiv, cond-mat/0109320 | | Services: | Forum | Review | PDF | Favorites | |
